Abstract

Marine plastic pollution is emerging as a potential hazard to global ecosystems and human health. Micro-fibers derived from synthetic textiles contribute a considerable proportion of plastic debris. Bio-polymers/bio-plastics have been proposed for the application of apparel products, yet their degradability, fate, durability and related environmental parameters are still elusive and need further exploration. Herein, we report the degradation behavior of poly(lactide acid)/poly(hydroxybutyrate) (PLA/PHB) fabrics, made from PLA/PHB multi-filament yarns, in subtropics marine seawater. The degradation experiments were performed under various parallel conditions including static seawater, aerobic seawater in dark box, aerobic seawater under sunlight, static seawater under ultra-violet light and aerobic seawater under ultra-violet light. Continuous mass loss of PLA/PHB fabrics as the immersion time in the seawater increased was confirmed. The hydrolysis rate of PLA/PHB fabrics accelerated in the presence of UV light and dissolved oxygen in the seawater. Moreover, the tensile strength of the PLA/PHB yarns dropped rapidly by 38.54-68.70% in spite of the mass loss percentage being from 9.57% to 14.48% after 2 weeks' immersion. All the PLA/PHB fabrics after two weeks' immersion exhibited similar ATR-IR spectra. Therefore, the degradability of PLA/PHB fabrics, in the marine surface water under the synergistic destructive effect of seawater, UV and dissolved oxygen, provides a pathway for more sustainable textile fibers and apparel products.

摘要

海洋塑料污染正成为全球生态系统和人类健康的潜在危害。合成纺织品产生的微纤维在塑料碎片中占相当大的比例。生物聚合物/生物塑料已被提议用于服装产品，但它们的降解性、归宿、耐久性及相关环境参数仍不明确，需要进一步探索。在此，我们报告了由聚乳酸/聚羟基丁酸酯（PLA/PHB）复丝纱线制成的PLA/PHB织物在亚热带海洋海水中的降解行为。降解实验在各种平行条件下进行，包括静态海水、暗箱中的好氧海水阳光、阳光下的好氧海水、紫外线下的静态海水和紫外线下的好氧海水。随着在海水中浸泡时间的增加，PLA/PHB织物持续出现质量损失得到证实。在紫外线和海水中溶解氧存在的情况下，PLA/PHB织物的水解速率加快。此外，尽管浸泡2周后质量损失百分比为9.57%至14.48%，但PLA/PHB纱线的拉伸强度仍迅速下降了38.54 - 68.70%。浸泡两周后的所有PLA/PHB织物均表现出相似的衰减全反射红外光谱。因此，在海水、紫外线和溶解氧的协同破坏作用下，PLA/PHB织物在海洋表层水中的可降解性为更可持续的纺织纤维和服装产品提供了一条途径。
